Subject: [PATCH v2] dt-bindings: arm: Convert Marvell CP110 System Controller to DT schema

From: "Rob Herring (Arm)" <[email-masked]>
Date: Wed, 22 Oct 2025 11:55:08 -0500

Convert the Marvell CP110 System Controller binding to DT schema
format.

There's not any specific compatible for the whole block which is a
separate problem, so just the child nodes are documented. Only the
pinctrl and clock child nodes need to be converted as the GPIO node
already has a schema.

Signed-off-by: Rob Herring (Arm) <[email-masked]>
---
v2:
- Keep documentation on individual clocks
- Drop 'io' from marvell,function values

-Marvell Armada CP110 System Controller
-======================================
-
-The CP110 is one of the two core HW blocks of the Marvell Armada 7K/8K
-SoCs. It contains system controllers, which provide several registers
-giving access to numerous features: clocks, pin-muxing and many other
-SoC configuration items. This DT binding allows to describe these
-system controllers.
-
-For the top level node:
- - compatible: must be: "syscon", "simple-mfd";
- - reg: register area of the CP110 system controller
-
-SYSTEM CONTROLLER 0
-===================
-
-Clocks:
--------
-
-The Device Tree node representing this System Controller 0 provides a
-number of clocks:
-
- - a set of core clocks
- - a set of gateable clocks
-
-Those clocks can be referenced by other Device Tree nodes using two
-cells:
- - The first cell must be 0 or 1. 0 for the core clocks and 1 for the
-   gateable clocks.
- - The second cell identifies the particular core clock or gateable
-   clocks.
-
-The following clocks are available:
- - Core clocks
-   - 0 0	APLL
-   - 0 1	PPv2 core
-   - 0 2	EIP
-   - 0 3	Core
-   - 0 4	NAND core
-   - 0 5	SDIO core
- - Gateable clocks
-   - 1 0	Audio
-   - 1 1	Comm Unit
-   - 1 2	NAND
-   - 1 3	PPv2
-   - 1 4	SDIO
-   - 1 5	MG Domain
-   - 1 6	MG Core
-   - 1 7	XOR1
-   - 1 8	XOR0
-   - 1 9	GOP DP
-   - 1 11	PCIe x1 0
-   - 1 12	PCIe x1 1
-   - 1 13	PCIe x4
-   - 1 14	PCIe / XOR
-   - 1 15	SATA
-   - 1 16	SATA USB
-   - 1 17	Main
-   - 1 18	SD/MMC/GOP
-   - 1 21	Slow IO (SPI, NOR, BootROM, I2C, UART)
-   - 1 22	USB3H0
-   - 1 23	USB3H1
-   - 1 24	USB3 Device
-   - 1 25	EIP150
-   - 1 26	EIP197
-
-Required properties:
-
- - compatible: must be:
-     "marvell,cp110-clock"
- - #clock-cells: must be set to 2
-
-Pinctrl:
---------
-
-For common binding part and usage, refer to the file
-Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt.
-
-Required properties:
-
-- compatible: "marvell,armada-7k-pinctrl", "marvell,armada-8k-cpm-pinctrl",
-  "marvell,armada-8k-cps-pinctrl" or "marvell,cp115-standalone-pinctrl"
-  depending on the specific variant of the SoC being used.
-
-Available mpp pins/groups and functions:
-Note: brackets (x) are not part of the mpp name for marvell,function and given
-only for more detailed description in this document.
